ServiceNow AI Control Tower

What ServiceNow calls a central hub to discover, secure, govern, observe, and measure AI

Short answer

Gemini Enterprise Agent Platform is Google Cloud’s platform to build, deploy, and govern agents; ServiceNow describes AI Control Tower as a central hub to discover, secure, govern, observe, and measure AI across an enterprise.⁠Source 1, Source 2, Source 3 Agent Platform’s runtime is billed by use; AI Control Tower is included in ServiceNow’s Foundation, Advanced, and Prime tiers.⁠Source 4, Source 5

Where each one sits

Six layers of running AI agents at a company, and what each product’s own public sources say it covers.

These aren’t the same kind of product

Where they overlap
Both keep a catalog of agents and MCP servers, can cut off an agent’s access, and keep audit logs.⁠Source 3, Source 6, Source 7, Source 8, Source 9, Source 10
Where they differ
Teams can also build and run agents on Agent Platform.⁠Source 1, Source 11 AI Control Tower’s connectors discover AI assets on external platforms; ServiceNow’s separate AI Agent Studio builds agents.⁠Source 12, Source 13
Running both
ServiceNow’s docs say its kill switch supports a Gemini Enterprise Agent Platform connector, for agents with unique identities only.⁠Source 14

What each one is

Gemini Enterprise Agent Platform

Gemini Enterprise Agent Platform is Google Cloud’s platform to build, deploy, and govern agents, an evolution of Vertex AI.⁠Source 1, Source 2 Agent Registry catalogs agents, MCP servers, and tools; Agent Identity can give agents on supported runtimes an identity; and Agent Gateway checks traffic against policy.⁠Source 6, Source 11, Source 15

ServiceNow AI Control Tower

ServiceNow describes AI Control Tower as a central hub to discover, secure, govern, observe, and measure AI across an enterprise, on the ServiceNow AI Platform.⁠Source 3 ServiceNow says it inventories agents, models, and MCP servers from ServiceNow and third parties, tied to your CMDB.⁠Source 3

The differences that matter

  1. How far each inventory reaches

    Gemini Enterprise Agent Platform

    Agent Registry works per Google Cloud project; agents on supported runtimes can be registered automatically, but agents elsewhere or in other projects need manual registration.⁠Source 29, Source 30, Source 31

    ServiceNow AI Control Tower

    ServiceNow says it auto-discovers agents, models, MCP servers, and datasets into one inventory tied to the CMDB; connectors you set up reach external platforms.⁠Source 3, Source 12, Source 32

    ServiceNow’s community documentation says only assets marked Managed get governance workflows, risk assessments, and monitoring.⁠Source 21

  2. Where access is enforced

    Gemini Enterprise Agent Platform

    By default, an agent’s outbound connections through Agent Gateway are blocked unless an IAM access policy grants them, and deny rules override allow rules.⁠Source 7, Source 11

    ServiceNow AI Control Tower

    ServiceNow’s community documentation says AI Gateway lets agents connect only to approved, active MCP servers, with tool-level policies by role, department, or data classification.⁠Source 16, Source 24

    Google says Agent Gateway’s inbound mode supports only agents deployed in Agent Runtime; ServiceNow’s community documentation says AI Gateway supports only remotely hosted MCP servers.⁠Source 11, Source 24

  3. Where data is kept

    Gemini Enterprise Agent Platform

    Agent infrastructure features, including Agent Runtime and Agent Gateway, keep data at rest, such as session history, in the supported location you select.⁠Source 33

    ServiceNow AI Control Tower

    AI Control Tower requires moving data from your instance to a central ServiceNow environment, possibly in another region, and potentially to a third-party cloud.⁠Source 34

    Separately, ServiceNow has a regional data routing option that sends LLM and SLM requests to data centers in your region.⁠Source 10

For security teams

What a security review asks, answered from each vendor’s public documentation.

Network exposureAgent Gateway’s ingress mode supports only Agent Runtime agents; outbound calls through it are checked against IAM access policy.⁠Source 11Discovery authenticates to external platforms with credentials you supply.⁠Source 32 Ports and egress requirements are not publicly documented.

Which to choose

Choose Gemini Enterprise Agent Platform if

  • You want to build, deploy, and govern agents on one platform, with Agent Studio and the open-source Agent Development Kit.⁠Source 1, Source 47
  • Your agents run on Google Cloud, where agents on supported runtimes, such as Google Kubernetes Engine, can be registered automatically.⁠Source 30, Source 31
  • You want Agent Gateway to block outbound connections unless an IAM policy grants them, with Model Armor scanning prompts and tool responses.⁠Source 11
  • You need agent data at rest, such as session history and memory bank entries, kept in a supported location you select.⁠Source 33

Choose ServiceNow AI Control Tower if

  • You run ServiceNow on a Foundation, Advanced, or Prime tier: each includes AI Control Tower, which ties AI assets to your CMDB.⁠Source 3, Source 5
  • You want one inventory of AI agents, models, and MCP servers across platforms, with connectors that discover AI assets outside ServiceNow.⁠Source 3, Source 12
  • You want a kill switch that revokes all active credentials of a managed agent on connected platforms, with an audit trail.⁠Source 9, Source 14
  • You want AI compliance content: ServiceNow’s pack covers the EU AI Act, NIST AI RMF, and California and Colorado AI laws.⁠Source 54

Questions buyers ask

Can ServiceNow AI Control Tower govern agents on Gemini Enterprise Agent Platform?

ServiceNow documents a kill-switch connector for Gemini Enterprise Agent Platform, for agents with unique identities only.⁠Source 14 Fully managing external AI assets in AI Control Tower (govern, secure, observe, measure) needs a separate AI Control Tower for Enterprise AI license.⁠Source 5

How is each one priced?

Agent Registry is free; skill scanning is billed from January 2027.⁠Source 23 Agent Runtime is billed by vCPU and memory hours; Agent Gateway egress, $0.085 per 15,000 requests.⁠Source 4 ServiceNow’s tiers include AI Control Tower; contact ServiceNow for pricing.⁠Source 3, Source 5 Its community documentation says usage-based costs may apply.⁠Source 24, Source 25

Do they support MCP and A2A?

Agent Registry catalogs MCP servers and A2A agents, and Agent Gateway carries MCP and A2A traffic; A2A agents on Agent Runtime are in preview.⁠Source 11, Source 31, Source 43, Source 44 AI Control Tower inventories MCP servers, and ServiceNow’s separate AI Agent Studio can connect external agents over A2A.⁠Source 3, Source 46

Can either one connect agents across organizations?

Agent Runtime agents can call outside agents through Agent Gateway.⁠Source 11 ServiceNow’s External Registries API lets any third-party system, such as Microsoft Agent 365, retrieve agents marked publishable.⁠Source 42 For both, bringing in another organization’s agents with access that organization controls is not publicly documented.
